`ZIPPO_CONTEXT_INVALID` error when querying 0x goerli swap api quote endpoint

Question

When querying the following endpoint and parameters: https://goerli.api.0x.org/swap/v1/quote?buyToken=0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee&sellAmount=1000000000000&sellToken=0x88D96a012a71f053041fe2BF27bC4703cebBB7b2

I get error like this:

 {
    "code": 100,
    "reason": "Validation Failed",
    "validationErrors": [
        {
            "field": "zippo",
            "code": 1010,
            "reason": "ZIPPO_CONTEXT_INVALID",
            "description": "Invalid zippo context"
        }
    ]
}

This endpoint is that I used before with the same params and it had worked well before. just I got the error from yesterday. I tested Mumbai endpoint too but it also returns the same error now.

Any help in understanding what is causing the issue would be helpful.

Remember to use your API key in the header. Ex:

curl --location --request GET 'https://goerli.api.0x.org/swap/v1/quote?buyToken=0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee&sellAmount=1000000000000&sellToken=0x88D96a012a71f053041fe2BF27bC4703cebBB7b2' --header '0x-api-key: <insert-your-key>'
